DUMPlNG-WAGON- Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed April 2, 1906. Serial! No. 309,336-

I 0 all whom it may concern:

Be it known that I, Jason W. SHEETS, a eitlzen of the United States, residing at Dayion, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Dumping-'agons; and I do declare the following to bc a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertnins to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in dumping-wagons in which the body of the wagon is provided with four downwardlyswinging bottom sections or doors whicharc hinged to the upright sides of the body and to a longitu dinal beamwhich ex tends throughout the length of the wagon-body.

The object of the. invention, primarily speaking. is to provide a dump-rigging which ma be applied to any of the wellknown an common forms of wi'igons without necessitating any changes in the structural features thereof.

A further object of the invention is to provide a dum -rigging which is easy of opera- Ition and su )stantial in all essential particuars.

The particular and essential characteristics of the invent-ion will be hereinafter more perticularly described in the specification and pointed out in the claims, reference being first made to the drawings, in which Figure I is a top plan view showing the intcrior side of the wagon-body and the mechanism or rigging for dumping the same. Fig. II is a longitudinal sectional view on the line y y of Fig. I. Fig. III is a cross-sectional view on the line a: m of Fig. I. i IV is a detached view of the foot-lever; h ig. V, an enlarged detail of the lower portion of the ratchet-pawl.

In a detail description of the invention similar reference characters indicate corresponding parts.

As hereinbefore stated, the body of the wagon requires nospecial construction over and above the upnght sides 1 1 with the front and rear inclosing ends 2 2, the said sides 1 1 projecting the usual distance beyond the front and rear end walls 2 2 to provide suitable space for the location of the dumping-rigging placed therein. Through the center of the body and extending longitudinally thereof is a beam 7, which is united at of the body. The swinging sections 4. and 5, forming the bottom of the wagon-body, are

of a suitable number of hinges 6.

As seen in Fig. III, the bottom of the wagon consists of four of these swinging sections. two of which are hinged to the beam 7 and 0 en downwardly from said beam and the ot ier two of which are hinged to the u right sides 1 and likewise open downward y. therefrom.

S designates a series of four truss-rods extending longitudinally of the swinging sec of said swinging sections. These truss-rods eient distance to aflord a connection with the actuating-chains 9,\'.l1ichnre secured thereto at the ends in any suitable way-such, for example, as by means of an eye 9, fixed to the ends of said truss-rods. The chains thus connected to the swingin sections pass upwardly at the ends of the body and canmeet with double rocker-arms 10, which are fixed to thc'rear and front shafts 11 and 12, Projecting downwardly from the rear shaft 11 and upwardly from the front shaft 12 are gmg, which is operated from the front shaft 12 by the following mechanism: A ratchet:v wheel 16 is pinned to a central portion of the 24 carried upon an operating-lever 27, w licli is loose upon said shaft 12.

in" sections through the arms 10, 13, and 14,

the shafts 11 and 12.

drops into the teeth of the ratchet-wheel 16 and holds said wheel and the shaft 12 in the position to which they are moved through the pawl 24. The primary pivot of this retaimng-pawl 21 is at 22 on the eictcrior sid of the front end wall of the wagon-bo and its ends to the stationary bottom portions .1"

are rigidly secured to the under sides of said. sections, with their ends PIOJGClLGd a. sutfirigid arms 13 and 14, which are connected to the exterior of one side of the body by means of a truss-rod 15. This forms the operating connection between the front and rear rigshaft 12 and is engaged by an angular 'awl By this means the shaft 12 is actuated to elevate the swing?- wiiich, as before stated, are rigidly secured to 21 designates a retaining-pawl which" hinged, respectively, to this longitudinal, beam? and to the upright sides 1 l by means tions 4 and 5. of which there is one for each it has a further pivotal connection at 20 too: '1 I slotted link 19, the latter being on t-Z 3- i the rearward angle of the footover The said foot-lever 171's loose upon shaft 12 1 between the rear roekerarm and the rear and carries a roll, stud. or pm 2%, which an- I ters the slot in the link 1!). The rear'aard angle or the lever 17 is engaged by a spring 18, which holds it normallv in the position shown in Fig. ll, wherein the stud or pin "is is in the lower end of the slotted link 12 Also pivoted to this slotted link 1!) at. the point 20 is a lilting-pawl 23, whieh rests upon a projection .ti. extending from the rear ard I wardly-extended portion, a ratehet-detent, a.

In a dumping-wagon, four bottom-sections hinged respectively, to a central bod beam and to the sides of the wagon-body, a primary and a secondary actuating-shaft arranged respeetively at the front and rear ends of the wagon-body, a double rocker-arm fixed to each of said shaft-s, chain connections between the rear rocker-arm and the. rear ends of the hinged body-sections, chain connections between the forward rocker-arm and the forward ends of said hinged bottom-sections, oppositely-extemlcd arms rigidly coni ratchet-pawl engaging said wheel, a foot-lenectcd to said shafts, a connection between said arms, ratchet devices for actuating the primary shaft to impart similar movements to the double rocker-arms to raise the four hinged bottom-sections, a. foot-lever, and

means controlled thereby -for releasing the i four bottom-scorespectively, to a longitudinal body, a i'rnntactuating-shaft and a rear -shaft, suitable connections between the front a tuating-shaft, and between the rearward ends of the four lunged bottom-sections and the rear shaft, :1 direct connection between a ratchet-wheel iixed to said actuating-shaft, a pawl, and lover cooperating with said ratchet-whcel to impart; movement to the a detentfor said ratchet-wheel, a lifting member engaging the actuating-pend of said ratchet-wheel, a foot-lever loose upon said front actuating-shalt, and connections between said foot-lever and said detent and said lifting member, whereb the detent and the ratchet-pawl are disengaged from the ratchet-whee when the foot-lever is depressed.

4. In a dumping-wagon, the combination of an actuating-shaft a rear shaft conn ted to said actuating-shaft, hinged sections forming the bottom of the wagon-body, rockervarms on the actuating-shaft. and the rear shaft, chain connections between the rockerarms and said hinged sections, a ratchetwheel fixed to the actuating-shaft, a driving JACOB W.
